Gastric cancer, a prevalent type of stomach cancer, is a major health issue worldwide. It develops when malignant cells form in the stomach lining, often leading to severe health implications. Early detection is crucial, as it can significantly improve treatment outcomes. In this blog, we will delve into the causes, symptoms, and risk factors associated with gastric cancer. We will also discuss treatment options, including chemotherapy for stomach cancer, emphasizing the expertise of Dr. Gopal Sharma, a leading oncologist at Max Vaishali, Ghaziabad.

What Causes Gastric Cancer?

The exact cause of gastric cancer remains unclear, however, several factors have been identified that may increase the risk of developing the disease:

1. Helicobacter Pylori Infection: This bacteria is a primary cause of stomach ulcers and has been linked to an increased risk of gastric cancer. Chronic infection can lead to changes in the stomach lining, paving the way for cancerous growth.
2. Diet: A diet high in smoked foods, salted fish, and pickled vegetables can increase the risk of stomach cancer. Conversely, a diet rich in fresh fruits and vegetables may help reduce this risk.
3. Obesity: Excess body weight has been associated with an increased risk of several types of cancer, including gastric cancer. The mechanisms behind this link may involve hormonal changes and inflammation.
4. Genetic Factors: A family history of gastric cancer can increase an individual’s risk. Genetic mutations and inherited syndromes may contribute to the development of the disease.
5. Smoking and Alcohol Consumption: Tobacco use and heavy alcohol consumption are significant risk factors for various cancers, including gastric cancer.
6. Previous Stomach Surgery: Individuals who have undergone surgery to remove part of their stomach may be at higher risk, especially if they have experienced significant changes in their digestive system.

Recognizing the Symptoms of Gastric Cancer

Early-stage gastric cancer may not present noticeable symptoms, making it difficult to diagnose in its initial stages. As the disease advances, symptoms may become more noticeable and may include:

Unexplained Weight Loss: Sudden and unintended weight loss may signal underlying health issues, including gastric cancer.

• Abdominal Pain or Discomfort: Persistent pain or discomfort in the stomach area, particularly after eating, is a common symptom.
• Nausea and Vomiting: Individuals may experience frequent nausea and occasional vomiting, which can be mistaken for less serious gastrointestinal issues.
• Loss of Appetite: A marked decrease in appetite or a feeling of fullness after consuming small amounts of food can indicate gastric cancer.
• Fatigue: Chronic fatigue that does not improve with rest may be an early sign of cancer.
• Difficulty Swallowing: Patients may experience discomfort or difficulty when swallowing, known as dysphagia.
• Jaundice: Yellowing of the skin and eyes can occur if cancer spreads to the liver, affecting its function.

Risk Factors for Gastric Cancer

Several factors can increase the likelihood of developing gastric cancer. While some, such as genetics, cannot be changed, others are modifiable. Awareness of these risk factors can empower individuals to make informed choices about their health and well-being.

1. Gender: Men are at a higher risk than women, with research suggesting that hormonal differences may play a role.
2. Chronic Gastritis: Long-term inflammation of the stomach lining can lead to changes that increase cancer risk.
3. Pernicious Anemia: This condition affects the body’s ability to absorb vitamin B12 and has been linked to an increased risk of gastric cancer.
4. Dietary Factors: As mentioned earlier, diets high in salt, smoked foods, and low in fresh fruits and vegetables can contribute to an elevated risk.
5. Occupational Hazards: Certain occupations, such as those involving exposure to rubber, coal dust, and specific chemicals, may increase risk.
6. Previous Cancer History: Individuals with a history of other cancers, particularly colorectal cancer, may have an increased risk of developing gastric cancer.

Diagnosis of Gastric Cancer

Diagnosing gastric cancer involves a combination of medical history, physical examination, and diagnostic tests. Some common methods used to diagnose stomach cancer include:

1. Endoscopy: A thin tube with a camera (endoscope) is inserted through the mouth into the stomach, allowing doctors to visually inspect the lining and obtain tissue samples (biopsies) for analysis.
2. Imaging Tests: X-rays, CT scans, and ultrasounds help assess the size and spread of the tumor, providing crucial information for treatment planning.
3. Biopsy: A biopsy is the definitive way to diagnose gastric cancer. The tissue samples collected during an endoscopy are examined for cancerous cells.
4. Blood Tests: While no blood test can definitively diagnose gastric cancer, certain tests may indicate underlying issues, such as anemia or liver function.

Treatment Options for Gastric Cancer

The treatment for gastric cancer depends on the stage of the disease, the patient’s overall health, and their preferences. Common treatment options include:

1. Surgery: If the cancer is detected at an early stage, surgical intervention may involve removing part or all of the stomach (gastrectomy). This is often the most effective treatment for localized gastric cancer.
2. Chemotherapy: Chemotherapy for stomach cancer in Delhi involves the use of drugs to kill cancer cells or stop their growth. It can be administered before surgery (neoadjuvant chemotherapy) to shrink tumors or after surgery (adjuvant chemotherapy) to eliminate any remaining cancer cells. Dr. Gopal Sharma at Max Vaishali, Ghaziabad, specializes in administering chemotherapy tailored to individual patient needs.
3. Radiation Therapy: Radiation therapy may be used in conjunction with chemotherapy or surgery to target specific areas where cancer cells are present.
4. Targeted Therapy: This newer form of treatment targets specific characteristics of cancer cells, such as genetic mutations, to inhibit their growth.
5. Immunotherapy: Immunotherapy harnesses the body’s immune system to recognize and attack cancer cells. It is an emerging treatment option for certain types of gastric cancer.
6. Clinical Trials: Patients may also have the option to participate in clinical trials exploring new treatments and therapies for gastric cancer.
